No. 619,899 Int. Cl. Ed 7/00 U.S. "Cl. 16-128 1 Claim ABSTRACT OF THE DISCLOSURE A butt-type hinge comprised of a pair of hingedly connected wings, each of the Wings having a plurality of cylindrical bosses extending therefrom and adapted to be snugly received in counterbored holes in the door and door jamb so that the bosses serve to support the least part of .the weight of the door.

This invention relates to improvements in the butt hinge, the improvements being for the sole purpose of facilitating installation of the hinge.

The main objects of this invention are:

First, to provide a hinge which can be installed with precision by a layman in a minimum of time.

Second, to provide a hinge which does not require any special tools for installation.

Third, to provide a hinge which does not require adjustment, even on original installation.

Fourth, to provide a hinge which gives a predetermined clearance between the door and the door jamb.

According to the invention, there is provided a hinge of the butt type which is comprised of a pair hingedly connected wings, each of the wings being a one-piece, generally planar, plate-form member of substantially uniform wall thickness and having a plurality of integral cylindrical bosses projecting in a direction substantially perpendicular to the plane of the wing. The sidewall of each boss extends substantially perpendicular to the plane of its wing and defines a circular cavity of constant diameter, which cavity is open at the end thereof adjacent the plane of said wing. The cavity has at its other end a bottom wall which is offset from the plane of the wing and which has an opening therethrough for receiving the shank of a screw.

Additional objects and advantages of this invention will become apparent from the following detailed description with reference to the accompanying drawings, in which:

FIGURE 1 is a front view of a thin hinge, in opened position.

FIGURE 2 is a sectional view of a thin hinge taken on line 5-5 of FIGURE 1.

FIGURE 3 is a front view of a thin hinge, in closed position, mounted on a partial section of the door and on a partial section of the door jamb.

FIGURE 4 is a sectional, view taken on line 8-8 of FIGURE 3.

FIGURE 5 is a sectional view similar to FIG. 2 and showing an alternate embodiment of the thin hinge.

FIGURE 6 is a sectional view similar to FIG. 4 and showing the mounting of the alternate embodiment of the thin hinge.

The hinge shown in FIGURE 1 discloses conventional features of a hinge, including the hinge wings 1, the mounting holes 2, the cylindrical pivot members 3, and the pivot pin 4, which extends through the cylindrical pivot members 3.

3,445,883 Patented May 27, 1969 It will be noted from FIGURE 2 that the hinge wings 1 are thin and this permits the hinge to be mounted on the surface of both the door 6 and the door jamb 7, as shown in FIGURE 4. Also the hinge wings I have projected, countersunk mounting holes 2 adapted to accept the conventional mounting screws, such as flathead woodscrews 9. The head 10 of the woodscrew 9 rests inside the projected, countersunk mounting hole 2. The thinness of the hinge wings 1 eliminates the need for carving a recess in both the door 6 and the door jamb 7 to accommodate the hinge as is conventional practice.

The simple procedure for mounting the hinge as shown in FIGURE 3 and FIGURE 4 is as follows: Using the hinge as a template the positions of the mounting holes 2 are marked on both the door 6 and the door jamb 7. At the marked location, pilot holes are made in both the door 6 and the door jamb 7 using common, conventional tools such as a brace and bit or a drill motor and drill bit. The pilot holes are then countersunk at the surface using a common, conventional countersink or the tip of a drill bit. Either wing 1 of the hinge is placed in position on the surface of the door jamb 7. The countersunk surfaces of the pilot holes accept the projected, countersunk mounting holes 2 of the hinge. Flathead woodscrews 9 are screwed into the pilot holes securing the hinge to the door jamb 7. The remaining wing 1 of the hinge is secured to the door 6 in like manner and the mounting is complete.

The above description illustrates the ease and simplicity of mounting the hinge. Thus it is apparent that the mounting can be preformed successfuly by either a layman or a carpenter with only the use of common, conventional tools.

FIGURE 3 and FIGURE 4 show the clearance 11 between the door 6 and the door jamb 7 to be equal to the combined thickness of the hinge wings I. The hinge is preferably made of strong, thin material. Thus the clearance 11 is held to a minimum suitable to accommodate the anticipated buildup of paint and/or varnish. Due to the clearance 11 being determined by the thickness of the hinge wings 1, adjustment of the hinge is not required, even on original installation. It follows that the clearance is uniform from top to bottom of the door and this uniformity adds to the appearance of the hung door.

Where greater support may be required, such as for example, on a solid core exterior door, an alternate embodiment of the thin hinge may be desired. The alternate design is shown in FIGURE 5 and FIGURE 6.

In comparison with FIGURE 2, the projected, countersunk mounting holes 2 of FIGURE 5 are further projected. Cylindrical shaped bosses 12 extend from the hinge wings 1 and terminate in the projected, countersunk mounting holes 2. When the hinge is mounted as shown in FIGURE 6, the bosses 12 rest inside counterbores formed at the surface of the pilot holes which have been made in both the door 6 and the door jamb 7. The counterbores are made using a common drill bit. The bosses 12 resting inside the counterbores share, with the woodscrew 9, in the support of all forces acting in planes perpendicular to the axis of the woodscrew 9. Thus the alternate design of the thin hinge provides increased support.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A hinge of the butt type, comprising a pair of hingedly connected wings, each of the wings consisting of a one-piece, generally planar, plate-form member of substantially uniform wall thickness and having a plurality of integral cylindrical bosses projecting in a direction substantially perpendicular to the plane of the wing, the sidewall of each boss extending substantially perpendicular to the plane of its wing and defining a circular cavity of constant diameter which cavity is open at the end thereof adjacent the plane of said wing, said cavity having at the other end thereof a transverse bottom wall which is offset from the plane of said wing, said bottom wall having an opening therethrough for receiving the shank of a screw, the cavity being adapted to receive the head of the screw, the wings being adapted to be mounted on the surface of a door and a door jamb with said cylindrical bosses being adapted to fit in counterbores therein so that the bosses serve to support at least part of the weight of the door.
